Germ and Bacteria Hot-Spots: 12 Things You Should Know

Dirty Door Handles
Claim: The bathroom-door handle on the public restroom is the germiest place.
False. Door handles actually have the least bacteria of any surface in public restrooms, according to a test by Chuck Gerba, PhD, a professor of environmental microbiology at the University of Arizona in Tucson. That's because, according to Gerba's tests, 68 percent of people wash their hands before leaving the restroom. To pick up something like salmonella, which can cause diarrhea, from someone who didn't wash up, you'd need a huge dose of the bacteria, says Larson. Also, most bacteria need a warm, moist environment to survive and can live on hard, dry surfaces for only one to two hours.
